Bore Gauge

A bore gauge is also known as dial gauge or bore dial gauge is a device used to determining the interior size of a hole.The range is 6mm,25mm,100mm.The least count is 0.001mm or 0.05mm and the accuracy is ±1µm, ±2µm.It is made of steel or stainless steel.It is extensively used in industries and laboratories.

Detailed Description for Bore Gauge

Bore Gauge is an instrument to measure the bore diameter of cylinders, pipes and bearings.

·         For internal measurements.

·         More convenient to use if supplied with the digital indicator with electronic scales.

·         Zero setting at any position & With data output interface.

·         Inch/Metric system conversion at any position

·         Steel-harden-tipped contact point for excellent durability

·         Adjustable anvils for wide measuring ranges. 

·         Equipped with digitaI indicator.

·         The length of L can be adjusted according to customer's requirement.

Traceability to international standards.

Type of Bore Gauge


Type of Bore Gauge

1.      Transfer Gauges

Transfer bore gauges consist of telescopic gauge and small hole gauges. In transfer type bore gauges, there are no scales on the tool. After the measurement with a transfer type bore gauge, the distance between contacts of the gauge are measured with a caliper or micrometer.


·         Telescopic Feeler Gauges

These are a range of gauges that are used to measure a bore's size, by transferring the internal dimension to a remote measuring tool. They are a direct equivalent of inside calipers and require the operator to develop the correct feel to obtain repeatable results.


·         Small Hole Gauges

Small hole gauges require a slightly different technique to the telescopic gauges, the small hole gauge is initially set smaller than the bore to be measured. It is then inserted into the bore and adjusted by rotating the knurled knob at the base, until light pressure is felt when the gauge is slightly moved in the bore. The gauge is then removed and measured with a caliper or micrometer.


2.      Dial Bore Gauge


A dial or vernier bore gauge measures a bore directly. The gauge has three symmetrical anvils that protrude from the gauge body that are connected to the dial or micrometer mechanism. As the knob is rotated it moves the anvils in or out with respect to the measurements. The knob usually has a slipping mechanism to take the feel out of the device and increase reliability between measurements. The measurement given is the mean diameter of the three anvils, and is usually good to 0.001 mm (3.9×10−5 in).
